Build and break things

Network infra engineer. I build tools that check whether the obvious explanation is actually true, and a few systems that just got to work.

A.V.E.N.G.E: edge vibration analytics

Go-based edge computing engine for real-time vibration analytics, inline signal compression, and predictive anomaly detection. Zero external runtime dependencies, zero-heap-allocation hot path. FFT → SDT compression → Z-score anomaly detection. MQTT → ClickHouse → Grafana, one docker compose up and u got the core stack.

Products

• railcast: Sparkle is the updater. Railcast is the backend it needs. live
• komposer: terminal UI for Docker Compose files with spec validation and security checks.
• platform-infra: self-service infrastructure for small teams on Cloudflare Workers + D1 + R2 & gh runners.

Investigations

friction → investigation → hypothesis → tool

• gai: dig working doesn't mean your process resolves the name the same way. Reconstructs the real getaddrinfo() decision path.
• khm: known_hosts is a database of server identities, not a cache.
• cfzt: one-command Cloudflare Zero Trust Tunnel cli.
• sidecheck: remote timing side-channel detection using statistics instead of a stopwatch.
• burnafterread: share a secret without giving the server access to it. live
• netconv: config conversion is about semantics, not replacing keywords.

Network forensics

Packets are evidence, not truth. Everything runs in the browser; PCAPs never leave your machine.

Zero Trust ain't just for infra. Don't trust this file either, verify it.
